You thought the snow and cold were behind us? Think again.

This time, though, the dip in temperature and possible wet snow flakes and/or sleet pellets would be short lived, occurring in the early morning hours Wednesday, right at the tail end of rain that's coming to Long Island Tuesday.

Look for cloud cover to increase through the day Monday, with patchy fog in some areas in the evening and possible isolated showers in the late evening, said Joey Picca, National Weather Service meteorologist based in Upton.

The highs will be in the 60s, according to the weather service.

By daybreak Tuesday "there's a good chance for rain showers Islandwide," he said, with periods of heavy rain forecast from midafternoon to around 8 p.m. Wind gusts could reach 30 to 35 mph with the heavier rain showers, he said.

With temperatures dropping overnight, any snow and sleet at the tail end of the rain would be dependent on the results of "a race between the cold air coming in and the precipitation moving out," he said. By the time cold-enough air is expected to arrive early Wednesday, the chances of precipitation will be 30 percent to 40 percent, he said.

Monday afternoon's forecast indicated "a very slight chance" of snow, more likely a rain/snow mix, and possibly just a parting shot in the final hour as precipitation ends, said Lauren Nash, also a meteorologist in Upton.

At any rate, no accumulating snowfall is expected, Picca said, and it's just possible that, given the timing of around 3 to 5 a.m., anything that does come will barely be noticed.

In total, liquid precipitation is expected to be mostly around 1.4 inches to just over 1.5 inches for the 8 p.m. Monday to 8 a.m. Wednesday time frame, with slightly higher levels in Nassau and western Suffolk, the weather service said.

Wednesday is expected to be sunny, breezy and cool, with highs in the upper 40s and lows right around freezing, Picca said.
